If you have multiple validation control and using ValidatorCalloutExtender,You might have exprience that it does not kick fly out all the time after your first submit click. Well, this sounds like bug and does not have straight fix on it.
Solution:
The funny part is you can solve this problem by simple by using "SetFocusOnError=True" on your respective RequiredFieldValidator. This is little bit tricky but it does solve your problem.

I wanted to merge two cell in excel 2003.Question is how ? This sounds like very simple things for professional user and but it took me a hour to figure out the solution. ere is what i did
1. I tryed few left click ,right click and search few buttons on excel tool bar and did not fond anything...Now it is time to search Microsoft Office site this is what i found
Merge or split cells or cell contents
OK very good i followed the steps and try to merge two cell....wait a minute where is "Merge and Center" button and where is "formatting" menu on tool bar.Somehow i guess it is pointing to "Format" menu on Tool but somehow i could not found it...
Did i missed something..Don't know ..Yes,your right eve i try the note section also but no hope..
Then i thought it is for excel 2007 i went and check the help targeted version of excel ...no it is for excel 2003
I have no clue which excel 2003 file is pointing this help article but definitely it sounds like something is missing here.I use excel 2003 but did not found useful to me.
Here is what i found to merge two cells
Select two cell >>right click on it ..? click on format cells
then click on alignment tab ..? "Merge Cell" and then click ok
I am using excel professional 2003 edition
if somebody has any idea please feel free to post comment here.

I was surprise to know that 'DateTime.Parse' does not parse fractions of a second and this was messing up our Dataview filter.Here is nice tips from furum.
The Select expression you are using uses DateTime.Parse internally.
DateTime.Parse does not parse fractions of a second, even if you were to include them in your expression.
I can't see DateTime.Parse ever being changed for backwards compatibility reasons. You basically have two solutions.
1. Truncate the DateTime to an exact second before inserting in your DataTable, e.g.:
|
|
locTimeVariable = TruncateToSecond(System.DateTime.Now.AddDays(i));
|
There are a number of ways you could implement the "TruncateToSecond" helper method. Here are two - you might like to test to see which is fastest:
|
|
static DateTime TruncateToSecond(DateTime dateTime)
{
return new DateTime(dateTime.Year, dateTime.Month, dateTime.Day, dateTime.Hour, dateTime.Minute, dateTime.Second, dateTime.Kind);
}
static DateTime TruncateToSecond(DateTime dateTime)
{
return new DateTime((dateTime.Ticks / TimeSpan.TicksPerSecond) * TimeSpan.TicksPerSecond, dateTime.Kind );
}
|
2. Alternatively you could specify a range of times from N to N + 1 second, for example:
|
|
"MyColumn>=#" + locTimeVariable.ToString(DateTimeFormatInfo.InvariantInfo) +
"# AND MyColumn<" + locTimeVariable.AddSeconds(1).ToString(DateTimeFormatInfo.InvariantInfo) + "#";

If you get this surprise error after converting the asp.net project.
This is what you need to do
Original
<%# Container.DataItem("ID") %>
Change to
CType(Container.DataItem, DataRowView)("ID").ToString
This solve your problem.
To set Option Strict in the integrated development environment (IDE)
On the Tools menu, choose Options.
Open the Projects and Solutions node.
Choose VB Defaults.
Modify the Option Strict setting.
To set Option Strict on the command line
Include the /optionstrict compiler option in the vbc command.

I was reading a document on web service and came a very good point on when to use web service and when not.
If you have something in your mind please feel free to put comment here...
Use Web Services:
o Communicating through a Firewall When building a distributed application with 100s/1000s of users spread over multiple locations, there is always the problem of communicating between client and server because of firewalls and proxy servers. Exposing your middle tier components as Web Services and invoking the directly from a Windows UI is a very valid option.
o Application Integration When integrating applications written in various languages and running on disparate systems. Or even applications running on the same platform that have been written by separate vendors.
o Business-to-Business Integration This is an enabler for B2B intergtation which allows one to expose vital business processes to authorized supplier and customers. An example would be exposing electronic ordering and invoicing, allowing customers to send you purchase orders and suppliers to send you invoices electronically.
o Software Reuse This takes place at multiple levels. Code Reuse at the Source code level or binary componet-based resuse. The limiting factor here is that you can reuse the code but not the data behind it. Webservice overcome this limitation. A scenario could be when you are building an app that aggregates the functionality of serveral other Applicatons. Each of these functions could be performed by individual apps, but there is value in perhaps combining the the multiple apps to present a unifiend view in a Portal or Intranet.
o When not to use Web Services: Single machine Applicatons When the apps are running on the same machine and need to communicate with each other use a native API. You also have the options of using component technologies such as COM or .NET Componets as there is very little overhead.
o Homogeneous Applications on a LAN If you have Win32 or Winforms apps that want to communicate to their server counterpart. It is much more efficient to use DCOM in the case of Win32 apps and .NET Remoting in the case of .NET Apps.

This is sounds very interesting.
